A new multilingual mailing list has been set up for people interested in translations of wikimedia content. You can sign up here :
http://mail.wikipedia.org/mailman/listinfo/translators-l
The list will announce new content for translation as soon as it is created, and provide a place to talk about the progress of translations. New content includes new Mediawiki: messages and sitewide notices, and important changes to pages on the wikimediafoundation site.
